The spec currently says:
* lowerBound - Creates and returns a new key range with lower set to lower,
lowerOpen set to open, upper set to undefined and and upperOpen set to true.
* upperBound - Creates and returns a new key range with lower set to undefined, lowerOpen set to true, upper set to value and and upperOpen set to open.
It should say the following in order to match the interface definition (change lower to bound and value to bound, respectively):
* lowerBound - Creates and returns a new key range with lower set to bound, lowerOpen set to open, upper set to undefined and and upperOpen set to true.
* upperBound - Creates and returns a new key range with lower set to undefined, lowerOpen set to true, upper set to bound and and upperOpen set to open.
